invention, to another pipe section 2, the pipe While I have illustrated a table constructed 55 according to my invention, I Want it understood that my invention is not directed nor limited to a table construction and that my invention is directed broadly to the fastening arrangement by which pipe sections used in the making of furniture frames are connected together in a detachable, easily assembled and easily dismantled manner, together with the idea of using the fastening device as a support for the table top, chair seat, or the like. Applying the invention, for instance, to a modernistic arm chair which is made of pieces of pipe deflected in any decorative style toV form the sides and arms of the chair, and which at the present time are interconnected by crosspieces forming the back as well as bottom supports, it will be seen that pipe sections forming the sides and arms can be made separate, and that the cross-pieces for connecting the same at the bottom or at the back can also be made in separate pieces, and provided at the point of manufacture with the dowels 3 and the rest of the construction described so that all the portions of the frame can be shipped in a compact package Where all the pieces can lie flat, one upon the other, to be assembled at the point of use, Furthermore, by my invention, if one part of the frame is damaged, the same can be removed either for replacement or for repair Without the necessity of transporting the entire piece of furniture.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

In a knock-down furniture frame formed ol separable pipe sections, means for detachably securing said pipe sections comprising a dowel fastened in the end of one pipe section and projecting into an adjacent pipe section, and a pin for securing said dowel to said last mentioned pipe section, said pin extending horizontally inwardly of the vertical plane of the adjacent pipe sections and constituting a support for a table top.
